Morehouse, Tllil'lntl, Calif., assignor to Adel Precision Products Corp., a corporation oi' California Application February is, 1943, vserial No. 476,093 9 claims. (C1. 24a- 74) This invention relates to clips for supporting the iiuid conducting and other conduit lines in aircraft, wherein the clips are provided with clasps for temporarily holding them on a structural part of the aircraft in position to be readily and easily secured thereto, and provision is also made for temporarily holding the clips in the de` sired position on the conduit until said clips are completely installed.

In my pending application for patent entitled Supporting clip for conduits, Ser. No.` 464,276,

'illed November 2, 1942, there is shown a clip of.

the character above described, wherein a latch member or 4hook is struck out from one of the two opposed ends of the conduit embracing strap for temporarily securing the two ends in position to hold the clip on the conduit,` and a clasp is formed integrally withI said one end for temporarily holding -the strap on the structural part to which it is to be secured.

In another of my pending applications entitled i Conduit clip and supporting bracket, Ser. No.

J I'he present. invention has for its primary object to provide a conduit clipwhich is similar to those hereinbefore described but subject to being on a conduit in preparation for temporarily much more lreadily and easily installed with a.

saving intime, labor.and costs, in that a temporary holding latch or hook member is provided mp in the desired position on the emicrania` both sub-assembly and direct installation* operaminer object is m provide 'a conduit clip of i the characterdeecribed wherein the separate which the latching hookis formed is ad.

iustably supported onone oftheen'ds'ofthe strap al by being pivoted=thereto, the latching hook inthepresentcasebeingaoformed anddisposed withrelaticntotheendsofthestrapthatregardless of the adjusted position of the clasp it will latch said ends together when they are moved toward one another into a predetermined position in which the strap is clamped on the conduit.

A further object is to provide a conduit clip such as described in which the clasp pivoted on one end of the conduit-supporting strap supports a nut as well as the latching hook, with the nut in position to be threadedly engaged with a bolt when the latter is inserted through the ends of the strap, the structural part of the aircraft and said clasp.

With the foregoing objects in view, together with such other objects and advantages as may subsequently appear, the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed, and illustrated by way of example in theaccompanying drawing, in which: l

Fig. 1 is a perspective view of a clip embodying my invention showing how the clip is positioned clamping and holding it thereon; y

Fig. 2 is a perspective view of the clip after being temporarily clamped on the conduit, show'- l ing the clip temporarily held on a structural part of lan aircraft by means of the clasp;

AFig. 4 is, a fragmentary enlarged rear elevation oi' the clasp and adjacent parts of the clip;

Fig. 5 is a front elevation with the clasp extending in the opposite direction from that shown in Fig. 1;

Fig. 6 is a fragmentary front elevation showing the clasp adjusted to embrace an inclined edge of a structural member; v

Fig. 7 is a vfragmentary plan view of the arrangement shown in Fig.6 as nally installed.

Referring to the drawing more specifically, it is seen that a conduit supporting clip embodying my invention includes a tensioned metallic strap l adapted to embrace a conduit 2, and provided Vwith opposed apertured ends l and l normally spaced apart and subject to being moved towards one another lto clamp the strap on the conduit. y As here shown the strap I is provided', with a cushion strip l of compressible insulation mate,- rial aii'ording a cushioned seat for the conduit,

there being an electrically conductive bonding..l strip t arranged relative to the strap and the cushion for contacting the conduit to bond the latter to the` metal strap for the purpose of harmlessly and without radio interference discharging static electricity into a metal structural member 1 of the airplane, to which member the ends of the strap are secured by a bolt 8 and a nut 9.

In accordance with this invention a separate U-shaped metal clasp I having apertured opposed legs I' and I0 is mounted on one of the ends, for example, the end 3 of the strap I, for embracing an edge portion of the structural member 'l of the aircraft to hold the clip temporarily in position to be secured to said member by means of the bolt 8 and nut 9. As here shown the clasp I 0 is pivoted on the end 3 by means of a hollow or tubular rivet I2 passing through the apertures in the leg I0 and end 3, whereby the clasp may be swung through at least 180 of arc for application of the claspto variously positioned edges of structural parts of the aircraft, Whether said edges extend horizontally, vertically or at various angles.

The nut 9 is clipped around and thus permanently mounted on the leg I0" of the clasp I0 so that when thee bolt 8 is inserted in place and turned it will thread into the nut thereby making it unnecessary to handle the nut in the olperation of completing the installation of the cip.

In order to hold the ends 3 and 4 of the strap in a position for temporarily clamping the clip on the conduit either before or after the clasp is mounted on the structural member 1, I provide on the clasp I0 a hook member I3 which is struck out from the leg I0' and the mid portion of the clasp. This hook extends substantially at right angles to the end 3 toward the end 4 and is on a line with the -longitudinal center line of the clasp and positioned close to the curved edge of the end 3 of the strap so that when the clasp is swung on its pivot the hook will traverse an arcuate path concentric with said'edge. The end 4 is correspondingly curved and is beaded or ribbed at the arcuate edge 4', the bead or rib insuring a good grip of the hook. The slightly inturned bill portion I3' of the hook is disposed so that when the end 4 is moved toward the end 3 into. a predetermined position the beaded or ribbed edge 4 will snap or may be moved past the bill I3' and become latched thereto, thereby holding the clip on the conduit. The ends 3 and 4 when thus held by the hook I3 have their apertures aligned so that the bolt 8 may be readily inserted and turned into the nut 9.

It is seen that the hook I3 is disposed in all positions of the clasp so that the end 4 may be held thereby in position to clamp the clip on the conduit.

As the strap I is tensioned, the ends 3 and 4 tend to spring when the end 4 is released after it is moved past the bil1I3' of the hook I3, thereby causing end 4 to spring outwardly into tensioned engagement with the hook and be held in position clamping the strap on the conduit. With the strap thus held the mounting of the clasp on the aircraft may be readily and easily effected or if the clasp is already mounted, the insertion .of the bolt and the nal installation operation of tightening the clip on the conduit and bolting it to the structural member 1 may b e easily and readily carried out.

It should be noted that after the 'ends are temporarily held together by the hook I3 on the clasp In; and -before the clasp is mounted on the structural member of the aircraft, said clasp may be swung on its pivot into the desired position throughout at least of arc without releasing the hook.

While I have shown and described a specific embodiment of my invention I do not limit myself to the exact details of construction set forth, and the invention embraces such changes, modifications and equivalents of the parts and their formation and arrangement as come within the purview of the appended claims.
